      Hello guys My name Is Jhan, Can i open a New Thread here I cant post new Thread jhanmhaykhel, you do not have permission to access this page. This could be due to one of several reasons:
      I have an acer aspire 4730z and its dead,, i open the laptop and search the defective parts and found that the switch(on/offbtn#) has 17v whats wrong with my motherboard...
      tnx in advance keep safe every one

        Thanks fddizon
        resistance in the shorted caps is 15 Ohms , two others caps in the middle have 50 Ohms .

          So short goes when CPU is not in correct?

          Tried another CPU?

          If so says there could be a short via the socket... Find a pinout for the socket type and check resistance of socket using a fine needle on DMM (Have been times I have found the internals of the socket have snapped and caused shorts.... Ended up with socket replacement, Shouldn't be an issue if you have the equipment to reball)

            15 ohms is normal
